3025EMC Master Control Switching & Channel Branding
Revision 3.0.3 Page 47
4.4.4. DVE
The section applies only if +DVE-2D (2 channel DVE) or +DVE-2D-2 (4 channel DVE) options are
ordered for the EMC. This configures the EMC to recognize the DVE and place it with the video
processing path of the EMC. Select the “Check Hardware” button to verify how many DVE channels
available. Based on the ordering option the correct configuration options are made available to the
user. This setting is saved with the channel configuration.
Non-default DVE Location: This check box allows the user to move the position of the DVE in the
video processing path from its default location before the Video Mixer. When checked,
the user can use the Location pull down menu to select the position. This configuration
setting will fix the position of the DVE functional block. This cannot be changed
dynamically via automation or manual control.
Frame Accurate DVE: This check box applies to interlaced video standards only
. When this option is
enabled this forces the 3025EMC DVE hardware to only update the DVE effect on every
interlaced frame and not every interlaced field. The overall length of the DVE effect
scaling/cropping/position is not
affected by this option.
4.4.5. Auxiliary Output
Please note: These parameters are only available when either the “Auxiliary” or
“Clean Output” is selected as described in section 4.4.2.
This parameter enables the user to select where in the video processing path they would like to route
either the Auxiliary or Clean paths from.
The user will select the Aux or Clean output, and with the pull down menu designate from where in the
processing path the source will be taken (illustrated in Figure 4-9).
